My current rig has the small 4.6L 2v. 4wd extended cab. I have towed my cherokee a few times with the stock gearing, 3.55...it was a serious dog, got 9 mpg with no power. Weighed in around 5500 lbs. Towed it with upgraded gear ratio 4.10 and the edge evolution. What a difference with power, plus much beter throttle response. Took it over some serious grades 5-6 percent, truck did not lose speed,60 mph, going up the hills, stayed in 3rd gear the whole time. Mileage was vastly improved, 12.5 average. The edge alone was an awesome upgrade for the transmission and throttle response, the gearing just made it that much better

 

What mode you running the edge in?

 

Level two. recommended for towing

 

thanks man this was really helpful!

 

No problem. With the edge evolution it get rid of that annoying throttle lag that these trucks are known for.
